[rdiff-backup-users] Update errors

[Charlie Strauss]

I'm using rdiff backup for the first time on a mac osx system.  One  
machine is running version 1.1.3 the other is running 1.1.4
while I have the remote disk locally mounted I'm not using that.  
Instead I'm running rdiff backup in the usual way via ssh rdiff- 
backup --server

I get two kinds of error messages.  One of them is an update error  
that differs from the kind discussed in the wiki (for log files and  
other rapidly changing files).
the files causing the error are old files that have not been touched  
in months.

the destination for the backup is an empty directory with no previous  
backups in it.

here's some sample error messages.  I get lots of these:
